bit of advice needed here. basically i want to fit an rcd 310 to my 54 plate t5. I know i will need to change the fascia and top tray which is no big deal as the newer inits are a different shape. My question is this - will it connect directly to my existing wiring or is it going to be more trouble than its worth? The reason for doing this is because i want to keep the factory look. Cheers for any help on this.
